Always enable identity in integration tests (#1298)

olix0r · web-flow · commit 4b3d4b8ae035 · 2021-10-05T08:35:06.000-07:00
In preparation of making identity mandatory, this change adds
a default identity that is used in all integration tests (unless
overridden by the test itself).

This change also regenerates existing TLS credentials used in tests.
